WKS Evo Circle PRO 6.5 kVA 48V Hybrid Inverter
The most advanced hybrid solar inverter of its generation
The WKS Evo Circle PRO is a latest-generation hybrid inverter designed for off-grid and hybrid solar installations. It combines three essential functions in a single device: a pure sine wave inverter, an MPPT solar charge controller, and a battery charger. This all-in-one architecture significantly simplifies the design and management of a photovoltaic system while ensuring high energy efficiency and exceptional reliability.
The WKS Evo Circle PRO stands out for its versatility, advanced connectivity, and its ability to operate in parallel for cumulative power outputs up to 39 kW.
This model is ideal for off-grid homes, hybrid systems with batteries, or industrial and commercial installations requiring a reliable and continuous power supply.
An all-in-one inverter for your energy independence
Designed to meet the needs of residential, professional, or isolated installations, the WKS Evo Circle PRO ensures a stable, clean, and continuous power supply, even without a grid connection.
Thanks to its 120 A MPPT technology and its wide photovoltaic input range (90 V – 450 V), it maximizes the use of available solar energy, guaranteeing an efficiency of over 93%.
Its dual output system allows for separate management of critical and secondary loads: your essential devices remain powered, while non-priority loads are activated only when solar production is sufficient.

Installation AdviceProper room ventilation is essential to ensure correct heat dissipation. It is recommended to use cables with an appropriate cross-section and suitable protections (DC circuit breakers, fuses, surge arresters) for the installation's power. Our technical teams can assist you with initial setup and commissioning. |
1. Concrete Usage – Real Installation Example
Example: Off-grid home with lithium batteries
An isolated 120 m² residence, equipped with:
- 12 x 450 W solar panels (total 5.4 kWp),
- 1 x WKS Evo Circle PRO 6.5 kVA inverter,
- A battery bank of two Delong or Pylontech Lithium batteries – 10 kWh.
The system works as follows:
- During the day, the WKS Evo Circle PRO directly converts solar production to power the house and recharges the battery via its 120 A MPPT controller.
- At night, it automatically switches to battery mode and continues to power essential equipment (lighting, refrigerator, freezer, telecommunications).
- In case of low battery or high consumption, the integrated AC charger triggers and recharges the batteries via a generator or the grid.
Result:
- 100% autonomy for most of the year,
- Electricity bill reduction of over 80%,
- No power outages, even in remote locations.
